Defendants made a calculated decision to settle this case almost two years ago, and a final judgment was entered pursuant to their agreement. To set that judgment aside, the law requires a showing of fraud on the court, not an imperfect investigation. Defendants have failed to identify even a single instance of fraud on the court, certainly none on the part of any attorney for the government. They repeatedly argue that fraud on the court can be found by considering the totality of the allegations. Here, the whole can be no greater than the sum of its parts. Stripped of its bluster, defendants' motion is wholly devoid of any substance.
